Why was Iblis (Satan) predisposed to disobedience and not repentance, while Adam was predisposed to repentance?

If the intention is that God compelled Iblis to disobey, then this is false; because God created him with will, desire, and ability, and he chose disobedience by his pure will. Therefore, the actions are attributed to him, as in the Almighty's saying: "Except for Iblis; he was arrogant and became one of the disbelievers." And God is just; He wrongs no one. As for the wisdom behind his creation, the fatwas have stated that God has profound wisdom in this.
